Hi folks, does anyone know what thread is used on the top of the yoke stem, the one that holds the top yoke to the steering stem? Further to that, does anyone have such a nut, and better yet lend or sell me a die to cut this thread?  Thanks in advance for any help.  Dave

Would help to know which model Montesa ... and year would be a help as the older ones changed a lot.

Hi, I can't be sure which model, it's oldish though. The thread that I am identifying is 25mm x 1.25 pitch. I am hoping to fit these forks, or at least the yokes to my new Bantam frame. Wasn't desperately impressed by what I got from Progressive so have decided to make my own. Have made the headstock to suit the yoke, rather than the other way round.   Dave
